LSC50: Colombian Sign Language Video and Inertial Measurement dataset

Abstract

Abstract In Colombia, approximately more than 500.000 people have disabling hearing loss, representing around 1% of the population in Colombia, and only 400 professional interpreters of Colombian Sign Language (LSC) are available in the whole country. In this data descriptor, we present a dataset with recordings of Colombian Sign Language (LSC) as an important effort to develop technologies that facilitate social inclusion and equity for the deaf community in Colombia. This dataset includes multimodal recordings of native and non-native signers signing different elements of the LSC lexicon. In particular, we provide recordings of video and inertial measurement units, along with detected body landmarks and computed information on the inverse kinematics of the upper body such as flexion, extension, and rotation of arms and wrists. This dataset is the first of its kind for LSC and it is key for the development of technologies needed to better understand the language and reduce communication barriers between people with and without hearing loss.
